http://en.wikipedia.org/wiki/Louis_Abernathy_and_Temple_AbernathyIn 1909 the boys rode by horseback from Frederick, Oklahoma, to Santa Fe, New Mexico, and back. Louis was nine, and Temple was five.
When the boys completed their Santa Fe journey, they began planning a cross-country horseback ride to New York City, again by themselves, to meet Theodore Roosevelt when he returned from his trip to Africa and Europe. They made that trip in 1910. They were greeted as celebrities, and rode their horses in a ticker-tape parade just behind the car carrying Roosevelt. While in New York, the boys purchased a small Brush Motor Car, which they drove, again, by themselves, back to Oklahoma, shipping their horses home by train.
In 1911, they accepted a challenge to ride horseback from New York to San Francisco in 60 days or less. They agreed not to eat or sleep indoors at any point of the journey. They would collect a $10,000 prize if they succeeded.
After a long trip, they arrived in San Francisco in 62 days, thereby losing the prize but setting a record for the time elapsed for the trip.
In 1913, the boys purchased an Indian motorcycle, and with their stepbrother, Anton, journeyed by motorcycle from Oklahoma to New York City. This was the their last documented adventure. Temple Abernathy died in 1986.
